We stained resected specimens from 117 patients with pulmonary adenocarcinoma for insulin-like growth factor-I1 (IGF-11) by the avidin-biotinperoxidase (ABC) method and evaluated the usefulness of IGF-I1 as a prognostic factor. The patients were classified into the IGF-I1 (+) groups showing staining

β¦ Synopsis
Platelet-derived growth factor (PDGF) in the resected pulmonary adenocarcinoma tissue of 88 patients was detected immunohistochemically by the avidin-biotin-peroxidase technique to determine whether or not it is a prognostic parameter. The 88 patients were divided into PDGF (-) and PDGF (+) groups according to the stainability of the factor. The PDGF (-) group included 39 patients and the PDGF (+) group 49. The 5-year survival rate was 53% for the PDGF (-) group and 17% for the PDGF (+) group (P < 0.01). These findings indicate that the stainability of PDGF can be a prognostic parameter for pulmonary adenocarcinoma.

## Abstract The purpose of this review was to determine whether imatinib mesylate (STI571, Gleevec) has a role in the treatment of osteosarcoma. The expression of plateletβderived growth factor (PDGF) receptor and its ligand was examined in a panel of surgical specimens obtained from 54 osteosarcom
